The geography of Kent impacts the road system in the 21st Century in exactly the same way as it affected the Romans who built the first roads almost 2,000 years ago. The long ridge of the North Downs that runs the length of the county east to west determines that the main roads run to either side. From London you can approach Lyminge along the M20 which runs south of the Downs and exit at Junction 11 which links directly to the A20. Alternatively, follow the M2 and then the A2 which run north of the Downs and exit for Barham. Lyminge and Etchinghill villages sit astride an unclassified minor road that runs the length of the Elham Valley north to south, linking the A2 to the A20. Whether approaching Lyminge from north or south, it is generally recommended to pick up this road rather than follow other routes which can involve some very narrow lanes.
